STREET AND STATION ANNUNCIATOR.

Specification of Letters Patent.

Patented Nov. 1'7, 15141.

Application filed August 10, 1914. Serial No. 856,052.

To all whom it may concern:

Be it known that 1, CHARLES P. BRADLEY, a citizen of the United States,residing at Pemberton, in the county of Burlington and State of NewJersey, have invented a new and useful Street and Station Annunciator,oi which the following is a specification.

The device forming the subject matter of this application is adapted tobe employed upon street railways cars and other vehicles, for thepurpose of disclosing to the passengers, the name of the street orstation which the vehicie is approaching.

One obiect of the present invention is to provide novel means foroperatively connecting the drums. which carry the inscribed web,with theactuating member.

Another object of the invention 1s to pro vide novel stop mechanism forlimiting the movement oi the flexible element or web which is assembledwith the drums.

Another object of the invention is to provide novel means whereby thedirection of movement of the web may be reversed, as is necessary whenthe caror vehicle runs back over a route previously traversed.

It is within the scope of the invention to improve generally and toenhance the utility of devices of thattype to which the presentinvention appertains.

With the above and other objects in view which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in thedetails of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed can be made within thescope of what is claimed without departing from the spirit of theinvention.

In the drawings :--Figure 1 shows the invention in section ;v Fig. 2 isa section taken at right angles to the showing of Fig. 1, parts beingbroken away; Fig. 3 1s a cross section on the line 33 of Fig. 1; Fig. dis a fragmental sectional detail illustrating the operative connectionbetween the gear train and one drum; Fig. 5 is a fragmental elevationshowing a modified form of the invention. v 1n carryin out the inventionthere is provided a boX-like casing l constituting i -support for thevarious movable elements of the device, the casing 1 being equipped atone side with a transparent plate Mounted in the casing 1 and extendedtransversely 1 and is mounted to rotate therein.

thereof are shafts 3 upon which are mounted drums at to which aresecured ratchet wheels 5 adapted to be actuated by pawls 6 pivoted topinions 7 journaled on the shafts 3, the pinions 7 meshing into gearWheels 8 carried by stub-shafts 9 supported 0d the casing 1.

Located between the gear wheels 8 is an actuating member 10 in the formof a rod.

The actuating member 10 is mounted to right line sliding movement in thecasing The actuating member 10 is provided with a rack 11. When theactuating member 10 is rotated on its axis, the rack 11 may be made tomesh into either of the gear wheels 8 and when the actuating member 10is moved in the direction of its length, that gear wheel '8 with whichthe rack 11 meshes, and the corresponding drum 4;, will be rotated, thegear wheel 8 meshing into the pinion 7 and the pinion 7 driving the druml through the instrumentality of the pawl 6 and the ratchet wheel 5. Aring or the like indicated at 12, is secured to one end of the actuatingmember 10. This ring 12 may be con nectedwith a cord or the like (notshown) so that, the structure may be operated from a distant point. Thering 12 coacts with the casing l, as will be evident from Fig. 1, tolimit the movement of the actuating member 10 under the action of aretractile spring 25, one end of which is secured as shown at 26 to thecasing 1, and the other end of which is secured to a washer 27 in whichthe actuating member 10 is journaled, there being'a collar 28 on theactuating member 10 against which the washer 27 bears. At one end, theactuating member 10 is provided with a handle 14 whereby the actuatingmember 10 maybe rotated on its axis, to cause the rack 11 to mesh witheither of the gear wheels 8.

A means is provided whereby the actuat ing member 10 will be preventedfrom rotating, saving when forcibly turned through the medium of thehandle 14. With this end in view, a support in the form of a block orthe like is attached to the casing 1 and carries a stiii spring tongue16. As indicated at 38, opposed sides of the actuating member 10 areflattened to coact with the free portion of the tongue 16. The functionof the spring tongue 16 is toprevent the rack ble structure, the cams,respectively, en-

gaging the stop to move the stop out of contact with the flexiblestructure when the rack is moved in one direction.

3. In a device of the class described, a pair of drums; a flexiblestructure terminally secured to the drums; an actuating trainoperatively connected with each drum and including a gear wheel; a rackprovided With opposed cams and having opposed, flattened side faces, therack being mounted to slide in the direction of its length and torotate, the rack meshing into one gear wheel, the rack being movable inthe direction of its length to actuate the said gear wheel and thecorresponding drum and being rotatable to cause the rack to mesh intoeither gear wheel; a spring adapted to coact at different times with theflattened side faces of the rack to hold the rack in mesh with therespective gear Wheels; a pivotally mounted stop adapted to coact withthe flexible structure, the cams engaging the stop at different times tomove the stop out of contact with the flexible structure when the rackis moved in one direction.

4. In a device of the class described, a rotatablymounted drum; anactuating train operatirely connected with the drum and including a gearWheel; a rack bar mounted to slide in the direction of its length andmeshing into the gear wheel, the rack being provided'with a flattenedside face and having a cam; a spring bearing against the flattened sideface of the rack to hold the same in mesh. with the gear Wheel; aflexible structure secured to the drum; a pivot ally mounted stopadapted to coact with the flexible structure, the cam being adaptedtoengage to move the stop out of contact with the flexible structurewhen the rack is moved in one direction.

In testimony that I claim the foregoing as my OWIIHI have hereto affixedmy signature in the presence of two witnesses.
